HEEL-ATTACHING MACHINE.

SPECIFICATION forming part of Letters .Patent No. 377,958, datedFebruary 14,1888,l

Application filed November 12, 1887. Serial No. 254,946. (No model.) v

To aZZ whom it may concern:

' Be it known that I, FREEBORN F. RAY- MOND, 2d, of Newton, in thecounty of Middlesex and State of Massachusetts, a citizen of the UnitedStates, have invented a new and useful Improvement in Heel-AttachingMachines, of which the following is a ful-l, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention relates especially to the mechanism or devices foroperating side-heelcompressing dies in a heel-attaching machine.

In the drawings, Figurel is a view, part in vertical section and part infront elevation, of a heel-attaching machine having the features of myinvention. Fig. 2 is a view in plan of the dies and their operativedevices, and in horizontal section of the frame of the machine and ofthe back post upon a level with the upper surface of the dies. Fig. 3 isa view in end elevation of the cross-head and of a lever for moving orturning one of the eccentrics, and in vertical section of the eccentric,the die-supporting block which it moves, and the carriage and supportbelow the same. Fig. 4

is a view in front elevation of one section of the heel-compressingmechanism. Fig. 5 is a view of the same parts represented in Fig. 1,showing the position of the parts at the completion ofthe compression ofa heel-blank upon the soles of a boot or shoe.

In the drawings, A represents the frame of the machine.

a is a cross-bed, upon which is mounted the sliding jack a', which hasthe jack-post a2 and supports the last or work-support a3.

B is the templet,and C the nail-carrier. They are supported upon thevertically-movable table b, which has a vertical movement upon the postb.

D is a reciprocating head. It carries a rotary head, d, which has an armforming the pressure-block d', an arm supporting a gang or group ofawls, d2, an arm supporting a gang or group of drivers, d3, and an armsupporting a top-lift holder and spanker, d4. These parts are like thosedescribed in Patent No. 316,894, and need not further be described here.

E is one side-compressing die, and E the other. Each die is mounted uponits respective slide-block e by means of a horizontal dovetail, whichfits the horizontal dovetail recess in the block. The block is mademovable in a carriage, e, by means ofan eccentric, e2, which passesthrough the enlarged hole e3 in the block and has bearings c4 in thearms e5 of the slide-block e?. The slide-block e has a dovetail, e7,that enters a dovetail recess, e8, in the upper surface of theslide-block e6. It also has the recess e9, across which the eccentricextends, and which receives the lower end, el, of a lever for turningthe eccentric. 'Ihel slide-block e6 is horizontally movable upon thestationarybed c, which is bolted to the beda of the machine (theslide-block e6 having a dovetaii projection, e, which enters a dovetailrecess, e, in the stationary bed c1 1)by means of the screw 614. Thisslide-block c6 is adjustable upon its bed e by means of the screw en.(See Figs. 1, 4, and 5.) The leverem has two arms, 615, and each armcarries a roll, el, at its upper end, (see Fig. 8,) and they are in linewith the bearing-blocks e, attached to the cross-head D, so that uponthe descent of the cross-head these blocks bearing against the rollscause the upper end of the lever am to be moved downward, turning theeccentric c2 and throwing the holding-block and die E inward.

The lever C is' connected with the head D by means of a link, em, whichis secured thereto by thumb-screws 619 in a manner to permit them to beeasily detached from the head. These links serve to keep the rolls incontact with the under surfaces of the blocks el, and also serve to drawthe'upper end of the lever upward upon theupward movement of thecross-head D, thereby serving to rotate .the eccentric e2 in areversedirection and moving backward the die-supporting block and die. Thisconstruction provides a very powerful compressing mechanism.

To obtain adjustments of the relation of the dies E E to each other itis simplyv necessary to adjust upon the beds e the slide-block e6 bymeans of their adj usting-screws el,-

In operation the shoe is placed upon the'jack with its outsoleuppermost, the heel-blank is placed in the die-recess, and the templetmoved into position over` the heel-blank and moved downward sufficientlyto bring its upper sur face into contact with the heel. Thepressureblockd is then moved into operative position. The machine is then caused tomake one reciprocation, the dies E E are caused to be moved inwardagainst the side edge of the heel, and the templet is at the same timemoved downward forcibly. The heel is then held confined upon the surfaceof the outsole, and while thus confined it is pricked, the nails fed,and attached. Thetemplet is then removed andthe top lift spanked.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United Statesl. The combination of the dies EE', the slide-blocks and eccentrics, and levers connected with theeccentrics for rotating them, substantially as described.

2. The combination,with the heel-attaching devices7 of dies E E', thedie-holding. blocks e,

cating crosshead D, having the bearingblocks e, substantially asdescribed.

4. The combination of the heel-attaching devices, theheel-side-compressing dies E E', their slide-blocks e, the blocks e",and means for adj usting them horizontally, the eccentrics e, leversel", and reciprocating cross-l1ead, substantially as described.
